- out the necessity for permanent securing Preferably the Wall 2 of thebod-y along 95 l means, and so that said strip may be applied theframing 3 or the door opening, is o'set .e by simplyshding said hookmembersl along outwardly, forming a groove or channel sald framingmember, said strlp with its 11 and the inturned edge portion of the wallwire reinforcement, bending freely in a lat- 1 which overlaps theoutturned edge poreral direction along curved portions of the tion ofthe wall 2 to formA the framing 100 peov Wall 3 for the door opening, isextended part Way across/one end of said channel 11 and then bentlaterally to form a ilange 12 eX- tending into and part Way across saidchannelu As such automobile bodies are usually constructed, an innersheathing 13 of iibrous material issecr-.red to the wall 2 and providedWith a fabric covering 14, the edge portion of such sheathingoverlapping and nearly closing the inner open side of the channel 11With the edge oi said fabric carried around the projecting edge of saidsheathing and secured thereto. A snbstantially closed channel 11 is thusformed in the framing or" the door opening and is continuous along thoseedges of said opening to Which it is desirable to apply a Weather striptor making a tight joint between .this training and the edge or edges ofthe door the inner side of the door.

The upper corner or corners oi such automobile body doors are oftencurved' instead oi being square and Where such doors are used, thetraining of the door opening is correspondingly curved, and in thepresent construction, the channel 11 Will be extended along such curveor curves With the flange 12 extending thereinto and correspondinglycurved, for a purpose hereinafter set forth. fis is the usual practice,the door is also provided `with an inner sheathing 15 of tibi-ousmaterial covered by a fabric covering 16 which is carried around andmade tast to the edge of such sheathing 'which is secured to the innerside of the door Wall 5 with said edge substantially even with the endWall ti olf said door.

The present 4Weather strip, which .is particularly adapted for use uponautomobile bodies constructed as above described but may be madeapplicable to other constructions, comprises a body strip 17 formed inany suitable manner, of rubber or other suitable lieXible material andof a length to entend along the entire length oi the framing oi' thedoor to which it is to be applied, This body is formed with a laterallyextending securing flange 18 and an oppositely extending projectingflexible edge portion 19 to extend across the craclr or opening betweenthe door edge and the iframing of the door opening, said flexible edgeportion being curved in the direction of its Width so that it will yieldreadily when the door comes into Contact with the free edge thereof,which edge is rounded and thickened to forni a contact bead 2O to engagethe inside of the door. rlhe strip is adapted to be secured to theflange 18 by means hereinailter described, the body 17 of said stripwhich connects said liange 18 and liexible edgey portion 19, beingthickened to give added strength with its inner side forming acontinuation of the outer surface of the Wall 3 of the framing of thedoor opening.

lThe opposite side of this body portion is formed to engage over the,edge ot the sheathing 13 and rest thereon when the strip is exed by theclosing of the door against the contact bead 20 on the edge of the projecting flexible edge portion 19 of the strip.

As shown, the exposed surface of the Weather strip Will usually becovered by a fabric strip 26 mainly for appearance sake, one edge ofsuch fabric strip, being carried around the bead 2O and the oppositeedge into the curved side of the body 17 beneath the projecting edge ofthe body sheathing 13, and this fabric cemented or otherwise securedilat upon the surface of the bead 20, edge portion 19 and body 17 towhich it is applied. ln so applying this fabric, the bead 20 provides arounded edge to facilitate the application of the fabric and pre- Ventit 'from Wrinlrling.

To reinforce the weather strip, and provide attaching means theretor andadd resistance to liexure oi the denible edge portion 19 thereof, aspring Wire is bent into a series oit loops and this Wire is embedded inthe rubber strip when said strip is molded or otherwise formed, with oneseries ot spring loops 21 extended into the curved edge portion 19 ofthe strip and curved to conform substantially to the lateral' curvatureof said edgeportion, and a series oi' oppositely eX- tending loops 22With one run ci each loop embedded in the flange 12 and the other run 23extending substantially parallel with said flange and spaced therefromto engage over the metal flange 18 With the runs 23 preferablyyieldingly engaging the inner side surface of said Bange and extendinginto the channel 11 of the framing of the door opening, to attach theWeather strip thereto, the inner end of each run 23 being bent laterally'and formed into loops 24 to connect with a like run below.. 'theseloops 24 being of a length to engage the end Wall of the channel 11 andhold the body of the Weather strip accurately andsecurely in place.

The spring fingers or loops 2l being -curved laterally of' the edgeportion 19 oi' the strip With said strip, and being flexible, lendresiliency to said edge portion to hold it in lirni contact with thedoor when the door is closed, and these spring lingers also tend toJfurther curve this edge portion When it is out ol contact `with thedoor, thus tur-- ther insuring iirm Contact with the door when swunginto engagementA therewith and Vflexing said edge. rlhe portions 25 oitthe Wire Which connect the' loops 21 and 22, are embedded in thatportion 17 oi the body which connects the securing tlange 18 withflexible edge portion 19 and lend strength to the strip -Vileatherstrips formed entirely oi' rubber or oi fabric covered rubber, soonbecome lSE ' said wall and hard and disintegrated, and it isdiflicult tosecure them evenly -and securely in proper relation to the door to forma tight jomt which will remain ti ht after extended use. By providingthe strip with a large number of attaching loops .24 to engage over themetal flange 12 of the framing, the strip .may be attached by simplyengaglng some or all of these loops over the flange and the attachingoperation may be facilitated by moving the strip endwise of the flange,bringing the succeeding loops into positlon to embrace said flange, theloops sliding onto said flange and along the same. If the framing iscurved at a. corner of the door opening, said flange 12 is also curved,and the strip being flexible, will follow this curve and pass around thecorner. Application of the weather stripl to the framing is thus greatlyfacilitated as no nailing or separate fastening means is required andthe loops 24 engaging the end wall of the framing channel 11, accuratelyosition the strip relative to tlie edge of the door, insuring evennessand roper positioning.

Obviously tliis weather strip may be applied to other than sheet metalstructures, and may be used in connection with sliding as well asswinging closures, and chan es may be made in the particularconstruction and arrangement of the weather strip itself withoutdeparting from the spirit of thel invention.

Having thus fully described my invention, what I claim is 1. A weatherstrip comprising a relatively" extending, in cross-section of saidstrip, at

substantially right angles to said flange and edge portion, whereby saidedge portion is offset outwardly from the plane of said flange.

2. A weather strip comprising a body portion formed of flexible materialand having an attaching flange integral therewith and extendinglaterally therefrom adjacent the inner edge thereof to seat upon astructure to which the strip is to be attached,V and a yieldable edgeportion extending laterally from the side of said body opposite thatprovided with said flange and integral with said'body ad'acent the outeredge of saidI body, said bo y being formed with a longitudinal groove inits side outwardly of and adjacent said flange to receive the edge ofsheathing to be applied to said structure.

3. A weather strip comprising an attaching flange adapted to seat upon amember to which said strip is to be attached, a flexible body integralwith said flange along the inner edge of said body and extendingoutwardly therefrom, a transversely curved flexible closure en agingedge portion extending laterally rom said ody and integral with theouter portion'of said body and lying in a plane offset outwardly by saidbody from the plane of the width of said flange, said body formin arelatively thick portion connecting said ange and edge p0rtion andextending at substantially .right angles to the planes of the width ofsaid flange and edge ortion, and a reinforcin wire formed with) loopsembedded in sai edge portion and loops embedded in said flange withportions connecting said loops and embeddedin said body ortion.

In testimony whereof I a x my si ature.
